IMPROVEMENT IN SECURING HANDLES TO TIN CUPS.

Specification forming part of Letters Patent No. 205,653, dated July 2,1878;

June 10, 1878.

To all whom it may concern:

Be it known that I, GEORGE \V. KNAPP, of Baltimore, in the county ofBaltimore and State of llfaryland, have invented a new and usefulImprovement in Securing Handles to Tin Cups, of which the following is aspecification:

My invention relates to certain improvements in the construction ofsheet-metal cups which are provided with handles.

Usually the handle has been attached to the body by means of rivets andsolder, and numerous efforts have been made to improve the method ofsecuring the handle to the cup.

The present invention has for its object to produce a cheaper and moredurable cup 5 and consists in the manner hereinafter described ofsecuring the handle.

Figure l is a perspective view of a cup embodying my improvement. Fig. 2is a view of the blank for the bottom. Fig. 3 is a view of same, showinga modified form of extension. Fig. 4 is a view of same, showing anotherform of extension. Fig. 5 is an edge view of bottom, the flange beingturned. Fig. 6 is a view of the handle. Fig. 7 is a side elevation ofthe cup previous to attaching the handle.

The letter a represents a cylinder, forming the body of the cup. b isthe handle; 0, the bottom, which is a disk or circular plate blanked outin the usual manner, and provided on the circumference with a radialextension or projection, d. (See Figs. 2, 3, and 4.)

The edge or circumference of the bottom is turned up, forming a flange,e, in the usual manner, (see Fig. 5,) the extension then assuming anupright position.

In blanking out the bottom the extension 61 is cut from the waste partof the sheet metal. Thus no additional cost is incurredin producing thisblank.

It will be observed the particular form of the extension (I is notmaterial, the object being to provide the bottom with an extension cutfrom the waste, to which the handle may be fastened.

The form of extension shown in Fig. 3 is adapted to have its edges V Vturn or lap over to inclose the lower part of handle, in stead of beinginclosed by the grooves of the handle.

application filed hen the bottom is placed on the cylinder the extension1 comes on the outer side. (See Fig. 7.) The edges of the handle areturned over inward in the usual manner, and thus form on each side atthe lower end a groove, f. (See Fig. 6.) The upper part of the handleturns downward, and forms a clamp, b, which is adapted to conform to andfit over the rim of the cup, as seen in Fig. 1, to which it is soldered,in this respect differing from the method of fastening shown in mypatent of December 4, 1877, in not passing the bent part I) through aslot below the beaded edge of can. The grooves f receive theupwardprojecting extension d. The bottom and cylinder are crimped in theusual manner, which binds together the lower part of handle and theextension, and the parts are then soldered.

By this construction the lower part of handle is firmly secured, and,should the solder be melted, will not become detached.

The handle is so bent as to require the upper part to be sprung over therim, thereby causing it to clamp the cup.

My improvement is equally well adapted to other vessels having similarhandlessuch, for instance, as stew-pans or sauce-pans.

Having described my invention, I claim and desire to secure by LettersPatent 1. The improvement in securing handles to tin cups, consisting ofa bottom having an upward-projecting extension inclosed in the sidegrooves formed upon lower end of the handle in the usual manner, as setforth.

2. The sheet-metal bottom, flanged in the usual manner, and providedwith the extension d, of any suitable shape, adapted to be fastened tothe handle of tin cups or other sheet-metal vessels, as set forth.

3. The improved sheet-metal vessel, consistin g of cylindrical body a,having a bottom provided with the upward-projecting extension d, whichis secured to the lower end of handle b, the upper part b of whichclasps the rim of the vessel, as shown and described.

GEORGE W. KNAPI.
